lMPRtlVEMENT IN IMPLEMENTS FOR UNCAPPING CARTRIDGE-SHELLS.

Specification forming part of Letters Patent No. 212,558, dated February 25, 1879 application filed December 16, 1878. i

Figure 1, perspective View; Fig. 2, longitudinal section.

This invention relates to a device for removing primers from metallic cartridges; and it consists in the construction, as hereinafter described, and more particularly recited in the claim;

A is the bed, having in its surface a semicylindrical recess, B, corresponding to the cartridge-cylinder, and near its outer end is a groove, a, corresponding to the flange of the head of the cartridge. Axially with this semicylindrical recess is a spindle, C, supported in a bearing, D, and so as to be moved longitudinally therein by means of a toothed segmental lever, E, working in a corresponding rack on the said spindle. In the forward end of this spindle is a pin, d, of less diameter than the central perforation through the head of the cartridge.

The cartridge-shell from'which the primer is to be removed is placed in the recess B with its flange resting in the groove a, the spindle C having been drawn back, as indicated in broken lines, Fig. 2. Then the spindle is forced forward by turning the lever. The pin 01 enters the perforation in the cartridge-shell, strikes the primer, and forces it therefrom, leaving the shell ready for recharging the primer. I

This device affords a simple and effective means of removing the primer, and may also be used for resetting the primer by simply reversin g the shell, the flange resting in the groove a as a support.

I am aware that devices have been made for mechanically removing primers by the arrangement of a spindle with a point to eject the primer, and therefore do not broadly claim such a device; but

What I do claim is-- The combination of the base, constructed with a semi-cylindrical recess, B, to receive the cartridge-shell, and annular groove d, near the outer end .of said recess, to receive the flange of an d support the cartridge longitudinally, and the longitudinally-movable spindle 0, provided at its front with the point at and with a device for moving said spindle, substantially as described.
